Safe to put toys back in her room??

A few months ago my now 20 month old DD was not going down for naps or bedtime very well...she would pretty much just start crying as we were walking towards her bed to lay her down. I read somewhere about taking toys out might help so we took the toys out of her room, although she never got up and played with toys at nap or bedtime, she would just cry.. (bedsides stuffed animals and a few books), it didnt really do anything, I dont think. It was 3 weeks or so after taking the toys out that she started to slowly get better at going to sleep. And now she is a champ:) But now I am wanting to put the toys back in her room, because DD #2 due in a few weeks and need to make room for baby swing and what not.
What do you think? Is it safe to put toys back in her room?
